To all whom it may concern:

Be it known that I JAMES OCoNNoa, a citizen of the United States, and a resident of New York, in the county of New York 5 and State of New York, have invented cer tain new and useful Improvements in Note- Sheet-Guiding Devices, of which the following is a s ecification.

This invention relates to note-sheetguiding devices for automatic musical instrudevice of the class specified etlicient in operation and simple in construction.

With these ends in view my improvements comprise arts and-combinations of parts illustrated in the accompanying drawn in which I have shown the preferred Figure 1 is a plan view of my improved device and Fig. 2 is an end view tiereof. Fig. 3 is a front elevation of a'modified form of my improvements. Fig. 4 is an end elevation thereof and Fig. 5 is a fragmentary plan view corresponding therewith.

M improvements may be mounted in the usua note-sheet supporting frame comprising opposite walls 2, 8 between which the usual tracker-bar 4 is supported for movement in the direction of its length, by the ears 5, 6 thereof being in sliding engagement with pins 7 8, projecting inwar ly from frame members 2 3, respectively. Said tracker-bar 4 ma be provi ed with the usual connecting tu es 9 and with suports such as brackets 10, 10 for shaft 11 l in parallel with said trac (er-bar. Said s aft 13 free to turn in said brackets, but is constrained against 'endwise movement relatively thereto by some convenient means as collars 12, 12. The opposite ends of said shaft 11 are provided with screw threads 13, 14, in engagement with nuts 15 16 fixed to frame mem ers 2, 3, respectively. Said threaded ends are of the same hand and pitch, whereby, when said shaft-is rotated, one end thereof is screwed into its corresponding nut the same distance that the other end is screwed out of its corresponding nut. Said screw threads being illustrated as ri ht hand, if shaft 11 is rotated in the direction of its. arrow, said shaft and tracker-bar 4 will be moved to the right, Fig. 1; if said shaft is rotated in the irection opposite to 5 that of its arrow, it and said tracker-bar will be moved to the left. Means for causing said shaft to rotate in one direction or the other, in accordance with lateral deviation of the note-sheet from its normal path of travel over the tracker-bar, comprise the following parts: Pivot-ed in bracket 10, with its axis parallel to shaft 11, is wheel 17 for frictional en agement with one ed e face of the noteeet when that sheet eviates to the left Fig. 1, from its normal ath of travel. The peripheral face of said wheel at its point of contiguity with the end of the tracker-bar is substantially in line with the face of said tracker-bar or slightly above that face. I preferably provide said wheel with a rim of rubber or similar material so that as the traveling note-sheet engages therewith said wheel is caused to rotate in the direction of its arrow. Fixed to said wheel is gear 18, driving car 19 fixed to shaft 11. Thus, when whee 17 is rotated in the direction of its arrow by enga ement with the note-sheet as it deviates to t 1e left, Fig. 1, said shaft 11 is caused to rotate in the direction op osite to that indicated by its arrow, whereby said shaft and trackerbar are moved to the left. This movementcontinues until wheel 17 has moved to the left a sufiicient distance to pass out from under the note-sheet, whereb said trackerbar is restored to its norma relation relatively to the note-sheet. At the other end of said tracker-bar, wheel 20, similar to wheel 17, but lar er, is fixed directly to shaft 11. Said whee 20 is of suflicient diameter to present its eri hery in continuity with the ace of trac erar 4. Thus, when the traveling note-sheet deviates to the right, Fig. 1, it will ride over onto the peri hery of said wheel 20 and rotate that wlieel and shaft 11 in the direction of the arrow on that shaft, thereby moving said shaft and tracker-bar 4 to the right. This movement will continue until wheel 20 has moved outfrom under said note-sheet when the tracker bar will have been restored to its normal relation relativel to the note-sheet.

In some cases l tion wheels on axes normal to the plane of the path of travel of the note-sheet, whereby said wheels are caused to rotate when en gaged by the edge of the note-sheet as it deviates laterally in its path of travel. By this arrangement it is convenient to make the said friction wheels 17 and 20 of the prefer to mount the friccloc wise direction, Fig. 3, by the engagement of the edge of the note-sheet therewith, shaft 24 is caused to rotate in a similar direction, thereby rotating shaft 11, Fi 5 i in a direction opposite to that indicated by its arrow, Fig. 5 whereby the tracker-bar is moved to the left, Fig. 3, thereby restoring normal relations between said tracker-bar and note-sheet. If, on the other hand, said note-sheet deviates to the right into operative engagement with the edge of wheel 20 said wheel will be rotated in anticlockwise direction, whereby shaft 11 is rotated in the direction of its arrow and the tracker-bar moved to the right, Figs. 3 and 4, thereby restorin the normal relation between the trackerar andthe note-sheet.

My improvedmechanism is exclusively mechanical as distinguished from pneumatically actuated mechanism and said mechanism may be very light in construction and sensitive in action, whereb a very slight frictional enga ement of eit ier of the opposite friction w eels by the note-sheet .will rotate that wheel to restore the disturbed relations to the normal.
